IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 173,663, dated February 15, 18764; application tiled November 13, 1875.

To all whom it may concern Be it known that I, JOHN R. PENDELL, of

, Ontario, in the county of Wayne and State of New York, have invented 'a new and valuable Improvement in Vash-Boilers; and I do hereby declare that-the following is a full, clear, and exact description otl the construction and operation'of the same, reference being had to the annexed drawings, making a part o1" this specification, and to the letters and figures ot' for which Letters Patent were granted to me dated May 6, 1873, No. 138,576, which are designed to cleanse the fabrics by means ot' boiling water elevated by means ot' steampressure, and discharged on top of the fabrics. The means pursued for accomplishing this ob ject I will now describe.

In the annexedv drawings, A designates the body ot'l the boiler, which has a broad daring rim, a., handles b b, and a draw-oft' cock, c, which latter is arranged as neer as practicable to the bottom ofthe boiler, and is used for drawing oit' from time to time unclean B designates a removable inverted pan, from the center otl which rises a tube, O, which is open at its top and bottom, and perforated at e. rIhe rim ot pan B isopen at several points, and the top ot' this pan is perforated at j'f. By theses means water is allowed to liow freely into the space g after descending through the fabrics. O designates a removable pan, which rests upon ledges 7L h, and forms a cover for the boiler. In the center ot' the pan C is a tubular valve, 7s, which, when it is opened, will allow cold Water to ow down through tube C into theV space g, the quantity ot' which water can be determined by gage-marks on the sides ofthe pan C. At the ends of the pan C are handles ZZ, and immediately below them are flanges m m, which will shield the hands from any steam which may rise from the boiler.

The hot water and steam rising through the tube O, and escaping from'its upper end, will l be suddenly cooled by contact with the bot tom of the pan C', thus causing a very rapid circulation ot' thewater in the boiler. Then the water in the boiler becomes too unclean for use it is'drawn oi by cock c, and the required quantity of clean water is allowed to flow into space g from the pan O.

The water in the boiler may be heated by steam from any well-known steam-generator, the boiler being placed in an opening in the top of the generator, or by any other convenient means, such as placing the boiler on top ot a stove.

What I claim as new, and desire to secure by Letters Patent, is-

The pan, having openings f, and provided with the pipe O open at its lower end and attached to its upper face, in combination with the water-feeding and steam-condensing pan O and waste-water cock c, substantially as described, and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
